Specification of Letters Patent.

Patented Jan. 19, 1915.

Application led April 23, 1914. Serial'No. 833,949.

To all 'whom it may concern.'

Be it known that l, FRANK B. BARBER, a citizen of the United States, residing at Fulton, in the county of Whiteside and State of Illinois, have invented certain new and useful Improvements in Work-Holders, of which the following is a specification.

My invention relates to -work holding devices adapted for use in la wide variety of arts, and has -for its object the provision of a plurality of vises, each of 'which is adapted to hold separate objects or different parts of the same object, said vises being simultaneously movable relatively to each other along a longitudinal axis and further being movable independently in a direction transverse to said rst mentioned axis, whereby articles held in said vises maybe retained in the proper positions to enable them to be operated upon by a workman, thus leaving both his hands free to facilitate the manipulation of his tools, or whereby different connected parts of an object vheld by the vises may be separated by the movement of the vises away from each other.

An important object is the provision of the aforementioned means for moving the vises transversely of the main axis, whereby, when the different parts of objects held within the vises are of different sizes, either or both vises may be moved transversely of the longitudinal axis of movement so that separation of the vises will cause the strain upon the objects to be exerted in a direction parallel to the longitudinal axis of movement. v

Vith these and other objects in view, such as simplicity, durability, efliciency, and the general improvement of the art, my invention consists in the novel construction and arrangement of parts as hereinafter described and claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of my device. and Fig. 2 is a cross section'thereof.

Referring more particularly to the drawings. the numeral 1 designates the supporting base of the structure. This base 1 comprises a lflat plate 2 having a dove-tailed tongue 3 on its upper surface. and upstanding` ears 4 on its ends. In these ears 4 are openings for the passage of a rod 5 which has on one half of its length a right hand screw thread 6 and on the other half a left hand screw thread 7. On one end Vof the rod.

rod 5 I provide a handle for rota-ting the My improved vises are disposed upon the base 1, one being disposed kupon the right hand screw-threaded vportion` 6 and the other being disposed upon the. left hand screw-threaded portion 7 of the rod 5. Each of the vises comprises a base block 9 provided upon its lower face with a dove.. tailed groove 10 for the reception of the tongue k3 on the base 1. The upper face of the block is provided with a tongue 11 which is disposed within a corresponding dove-tailed groove formed in the bottom portion of the upper section 12 of the vise. The upper section 12 comprises the usual movable vjaw 13 and the fixed jaw 14 operated by the usual screw and handle 15. The upper section 12 of each vise is moved upon the base block l9 by means of a screwthreaded lrod lipassing through the block 9 and provided upon its end with an op erating handle 17. The upper section 12 is further provided at its forward portion with a downwardly extending apron 18 provided with an aperture 19 for the passage of the reduced end 20 of the screw 16.

From'the foregoing it will be seen that the vises being in the position shown in the drawings, rotation of thehandle 8 and consequently the rod 5, will cause the vises to v be moved toward or away from each other depending upon in which direction the. handle 8 is turned. It will also be observed that rotation of the handle 17 will cause the upper section 12 of either vise to be moved upon the base block l9 in a plane at right angles to the axis of the previously de scribed longitudinal movement.

In use for instance when it is desired to braze or solder two metallic pieces to each other the pieces are gripped between the jaws 13 and 14 of the vises which are then` separated or brought together as required by moving the handle 8 until the ends or other desired portions of said metallic pieces shall come into contact whereupon the brazing or soldering may be readily accom-y plished by the operator. This device may 'be used for a wide variety of purposes more or less analogous to the instance mentioned. The device may be advantageously used for straightening wires, rods, shafts and the like, b v gripping the ends between the jaws 13 and 14 and then turning the handle 8 to separate the vises, thus causing longitudinal` together or secured in any other manner.`

This action is accomplished by gripping the portions to be separated between the jawsV 13 and 11i and then rotating the handle 8 for moving the vises apart.

'lf he fact that the upper sections 12 of the vises may be moved upon the base block 9 is of great importance as for instance if two objects to be stretched or pulled apart are of different sizes it is necessary to move one or both ot the upper sections 12 upon the base block 9 in order that the separating strain may be exerted in alinement with the longitudinal axis of the base 1 and rod 5 as otherwise the separating strain would not be uniform and would be lacking somewhat in eliiciency.

Having,` thus described my invention what l claim is:

l. t worlr holder comprising a base, a pair ont vises slidably mounted on said base, and mechanical means for moving said vises longitudinally and transversely.

A. work holder comprising a base, a pair of vises slidably mounted thereon. and means for moving` said vises longitudinally and transversely, said means comprising' one screw connectingr both vises for longitudinal movement on said base and one screw on each vise for transverse movement on the base block of said vises, and means for causinn` a simultaneous movement of said vises toward or from each other.

A work holder comprising a longitudinal relatively stationary base and vises adapted to i'it on said base., said vises having; jaws at their tops operated by a screw rod, and adapted to move longitudinally on said base by means of a screw rod provided with right and left hand screw-threaded portions, and each oil said vises having a. screw rod inserted for transverse movement on their base blocks.

fr. A work holder comprising a longitudinal base, a pair of vises slidably mounted thereon longitudinal thereof, 'screw operated means for moving, said vises, jaws at the top of said vises and screw rods for operating' said jaws, and means for moving' the upper sections of said vises in a direction at right angles to the axis ot said base, said last mentioned means comprising a screw rod passing` through the base blocks of the vises.

5. A work holder comprising,f a base, a plurality of vises slidably mounted thereon, screw operated means for simultaneously moving said vises toward or from each other. and means whereby the body portions of said vises may be moved in a direction at right angles to the axis oic said base, said means comprising` threaded screw rods passing;` through the base blocks of said vises.

6. A worlr holder comprising a base, a pair oi vises slidably mounted thereon. and a rod provided with right and left hand screw-threaded portions, each portion enraging one of the vises whereby said vises may be simultaneously moved toward or from each other. each of said vises compris in?, a relatively stationary base, and ay body section slidable upon said base portion in a direction at right angles to the direction of bodily movement of said vises.

7. A work holder comprising' a longitudinal base, vises slidably mounted on said base, each of said vises having a base block7 a body portion slidably mounted on said base block moi/'able transversely of said longitudinal base, and screw operated gripping; jaws on said body portion.

8. work holder comprising a longitudinal base, a dove-tailed tongue on said base, a plurality of visesy slidably mounted on said base, each of said vises having base blocks, said base blocks having dove-tailed slots for slidable connection with said dovetailed tongue on said longitudinal base and screw means for simultaneously operating` said vises.

9. A work holder comprising' a longitudinal base, a plurality of vises slidably mounted on said base, each of said vises having a base block., a body portion, and screw operated gripping jaws, said base block having a dove-tailed tongue on its upper face, and said body portion having; a dove-tailed groove tor slidably connecting with said base block, and screw means for moving said body portion on said base blocl transversely of said longitudinal base.
